Description

Die Erfindung betrifft ein Maischgefäß gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a mash vessel according to the preamble of claim 1.

Das Maischen ist ein wichtiger Vorgang bei der Würzeherstellung. Die Aufgabe des Maischprozesses liegt in einem bestmöglichen Vermischen des Schrotes und des Maischwassers. Die im Malz vorhandenen gewünschten Inhaltsstoffe sollen optimal in Lösung gebracht werden.Mashing is an important process in wort production. The task of the mashing process lies in the best possible mixing of the meal and the mash water. The desired ingredients present in the malt should be optimally dissolved.

Die bekannten Maischgefäße, wie z. B. Maischpfannen oder Maischbottiche, weisen einen kegelförmigen Boden auf, der sich nach unten verjüngt. Zur besseren Durchmischung ist ein Rührwerk vorgesehen. Oft ist der Boden auch als Heizfläche ausgebildet. In Fig. 5 ist ein Maischgefäß ohne Dunstabzug schematisch dargestellt, wie es aus dem Stand der Technik bekannt ist. Die Maische bzw. Reinigungslösungszufuhr und -abfuhr befindet sich in der Mitte des Bottichs. Der konventionelle Boden 9 weist eine aufwändige Konstruktion auf, wobei eine Vielzahl von sich radial erstreckenden Querstreben nötig sind. In der Mitte des Bottiches ist das Rührwerk 1 vorgesehen, das hier zwei sich radial nach außen erstreckende Rührflügel umfasst.The known mashing vessels, such. As mash pans or mash tuns, have a conical bottom, which tapers downwards. For better mixing a stirrer is provided. Often the floor is also designed as a heating surface. In Fig. 5 a mash vessel without extractor is shown schematically, as it is known from the prior art. The mash or cleaning solution feed and discharge is located in the center of the tub. The conventional floor 9 has an elaborate construction requiring a plurality of radially extending cross braces. In the middle of the tub, the agitator 1 is provided, which here comprises two radially outwardly extending stirring blades.

Es hat sich herausgestellt, dass die Durchmischung der Maische im oberen Bereich des Bottichs unzureichend ist. Dies ist insbesondere bei hochviskosen Maischen, wie sie bei High-Gravity-Verfahren verwendet werden, der Fall.It has been found that the mixing of the mash in the upper region of the tub is insufficient. This is the case in particular with high-viscosity mashes, as used in high-gravity processes.

Darüber hinaus ergibt sich der Nachteil, dass für kleine Teilmaischemengen auch der Boden des Maischebottichs beheizbar sein muss. Außerdem ist bei sehr kleinen Maischemengen eine Durchmischung durch die umlaufenden Arme des Rührwerks 1 nicht möglich, da die Arme nicht effektiv im unteren konisch zulaufenden Bereich wirken. Im unteren Bereich des Bottichbodens muss darüber hinaus eine Auslaufschüssel vorgesehen sein, so dass die Konstruktion des Maischgefäßes kompliziert ist. Außerdem ist es von Nachteil, dass sich die Maische in der Auslaufschüssel absetzt.In addition, there is the disadvantage that for small Teilmaisherengen and the bottom of the mash tun must be heated. In addition, with very small amounts of mash mixing by the rotating arms of the agitator 1 is not possible because the arms do not effectively act in the lower tapered region. In addition, a discharge bowl must be provided in the lower region of the tub floor, so that the construction of the mashing vessel is complicated. In addition, it is a disadvantage that the mash settles in the outlet bowl.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Maischegefäß bereitzustellen, das einen sehr einfachen Aufbau aufweist und auch hochviskose Maischen oder kleine Teilmaischemengen zuverlässig durchmischt.Proceeding from this, the present invention has the object to provide a mash vessel, which has a very simple structure and mixes even high-viscosity mash or small Teilmaiansengen reliable.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention, this object is solved by the features of claim 1.

Das erfindungsgemäße Maischegefäß erlaubt eine gute Durchmischung der Maischen. Der Boden kann einfach realisiert werden und bedarf keiner aufwändigen Verstrebung. Dadurch, dass der Boden im Vergleich zum Stand der Technik umgekehrt eingesetzt ist, und darüber hinaus noch unter einem bestimmten Winkel in Richtung zur Mittelachse des Gehäuses eingesetzt ist, verläuft die Umfangskante des Bodens in einer Ebene, die zur Horizontalebene geneigt ist. Unter Horizontalebene ist hier die Ebene zu verstehen, die senkrecht zu der Gefäßwandung steht. Das heißt, dass die Maische gut vom tieferen Bereich aus ablaufen kann, ohne dass Maischereste im Maischegefäß verbleiben. Dadurch, dass der Boden vom Umfang aus betrachtet schräg in Richtung Mittelachse L des Gehäuses nach oben verläuft, ergibt sich unterhalb des Bodens ein Hohlraum, der Platz für weitere Elemente bietet. Die Wellenabdichtung (Stopfbuchse) des Rührwerks kann direkt im obersten Bereich des Bodens, beispielsweise einer Kegelspitze eingeschweißt werden. Die bisherig verwendete Auslaufschüssel kann komplett entfallen. Die Bauhöhe des Gefäßes verkleinert sich, was gerade bei Sudhäusern mit niedriger Podesthöhe von Vorteil ist.The mash vessel according to the invention allows a good mixing of the mash. The floor can be easily realized and requires no elaborate bracing. The fact that the bottom is used inversely compared to the prior art, and is also used at a certain angle in the direction of the central axis of the housing, the peripheral edge of the bottom extends in a plane which is inclined to the horizontal plane. By horizontal plane is meant the plane which is perpendicular to the vessel wall. This means that the mash can drain well from the deeper area without any leftover mash in the mash jar. Due to the fact that the bottom, viewed from the periphery, extends obliquely upwards in the direction of the central axis L of the housing, a cavity results below the floor which provides space for further elements. The shaft seal (stuffing box) of the stirrer can be welded directly into the uppermost area of the floor, for example a cone point. The previously used outlet bowl can be completely eliminated. The height of the vessel is reduced, which is particularly advantageous in brewhouses with a low platform height.

Gemäß einer bevorzugten Ausführungsform ist der Boden als ein sich nach oben verjüngender Kegel oder Kegelstumpf ausgebildet, dessen Grundfläche die Mittelachse des Gehäuses unter einem Winkel 120° > γ > 90° schneidet und oval ist. Ein solcher Boden kann besonders einfach gefertigt werden.According to a preferred embodiment, the bottom is formed as an upwardly tapering cone or truncated cone whose base surface intersects the central axis of the housing at an angle 120 °> γ> 90 ° and is oval. Such a floor can be made very easy.

Gemäß einem besonders bevorzugten Ausführungsbeispiel der vorliegenden Erfindung ist die Rührwerkachse unter einem Winkel zur Mittelachse L des Gehäuses geneigt, wobei vorzugsweise der Winkel α, unter dem die Rührwerkachse zur Mittelachse L geneigt ist, dem Winkel α entspricht, unter dem der Boden geneigt ist. Zumindest aber sind Rührwerkachse und Boden in die gleiche Richtung geneigt. Dadurch, dass die Rührwerkwelle schief steht, ergibt sich eine erheblich bessere Rührwirkung in Kombination mit dem schräg stehenden Boden.According to a particularly preferred embodiment of the present invention, the agitator axis is inclined at an angle to the central axis L of the housing, wherein preferably the angle α at which the agitator axis is inclined to the central axis L corresponds to the angle α at which the bottom is inclined. But at least agitator axis and ground are inclined in the same direction. The fact that the agitator shaft is tilted, results in a significantly better stirring in combination with the sloping floor.

Vorteilhafterweise umfasst das Rührwerk mindestens einen sich radial nach außen erstreckenden Arm. Dabei verläuft der mindestens eine Arm nach unten und ist vorzugsweise im Wesentlichen parallel zur Oberfläche des Bodens um die Rührwerkachse umlaufend angeordnet. Mit einer solchen Konstruktion kann die Rührwirkung weiter verbessert werden. Es können hierzu konventionelle Rührflügel verwendet werden, die einfach nach unten gezogen werden, so dass herkömmliche Bauteile verwendet werden können und sich keine bedeutende konstruktive Änderung des Rührwerks ergibt.Advantageously, the agitator comprises at least one radially outwardly extending arm. In this case, the at least one arm extends downwards and is preferably arranged to run around the agitator axis essentially parallel to the surface of the bottom. With such a construction, the stirring effect can be further improved. Conventional agitator blades can be used which are simply pulled down so that conventional components can be used and there is no significant structural change in the agitator.

Die vorliegende Erfindung ermöglicht, dass der Boden unbeheizt ist, was erhebliche konstruktive Vorteile mit sich bringt. Sehr kostengünstig kann nämlich eine Heizung am Umfang im oder am Gehäuse angeordnet werden. Insbesondere dann, wenn die Heizung rund um den Wirkbereich des Rührwerks angeordnet ist, können auch sehr kleine Teilmaischmengen gut erhitzt werden. Unter Wirkbereich des Rührwerks versteht man hier den Bereich zwischen Boden und dem oberen Ende der Rührflügel.The present invention allows the soil to be unheated, which brings with it significant structural advantages. Very cost-effective, namely, a heater can be arranged on the circumference in or on the housing. In particular, when the heater is arranged around the effective range of the agitator, very small Teilmaischmengen can be well heated. The effective range of the agitator is understood to mean the area between the bottom and the upper end of the agitator blades.

Wenn die Heizung mehrere unabhängig voneinander regelbare, übereinander angeordnete Heizabschnitte aufweist, kann gezielt in Abhängigkeit der Maischmenge geheizt werden. Verwendet man beispielsweise nur kleine Teilmaischmengen, so ist es ausreichend, wenn in einem Bereich des Wirkbereichs des Rührwerks geheizt wird. Unbefüllte Bereiche des Bottichgehäuses werden dann nicht geheizt.If the heater has a plurality of independently controllable, superimposed heating sections, can be selectively heated depending on the mash. If, for example, only small amounts of mash are used, then it is sufficient to heat in a range of the effective range of the agitator. Unfilled areas of the tub housing will then not be heated.

Es ist vorteilhaft, wenn die kegelförmige oder kegelstumpfförmige Bodenfläche unter einem Winkel β von 5 bis 30° zur Kegelgrundfläche geneigt ist, da der Boden dann selbsttragend ist. Eine besonders gute Stabilität ergibt sich in einem Winkelbereich β von 10°-20°.It is advantageous if the conical or frustoconical bottom surface is inclined at an angle β of 5 to 30 ° to the cone base surface, since the soil is then self-supporting. A particularly good stability results in an angular range β of 10 ° -20 °.

In besonders vorteilhafter Weise erlaubt der erfindungsgemäße Boden, dass der Zulauf für die Maische nicht mehr im Inneren des Gehäuses vorgesehen ist, sondern seitlich im Gehäuse ,insbesondere im Wirkbereich des Rührwerks angeordnet ist. Der Zulauf kann auch von unten durch den Boden verlaufen oder von oben durch ein Zulaufrohr, das im Bereich der Seitenwand nach unten läuft. Somit wird die Verrohrung deutlich einfacher, da Eintritte z. B. von der Mühle am Umfang verteilt werden können.In a particularly advantageous manner, the bottom of the invention allows that the feed for the mash is no longer provided inside the housing, but is arranged laterally in the housing, in particular in the effective range of the agitator. The inlet can also run from below through the floor or from above through a feed pipe which runs down in the region of the side wall. Thus, the piping is much easier because entries z. B. can be distributed by the mill on the circumference.

Der Maischeablauf kann vorteilhafterweise im Boden an der tiefsten Stelle des geneigten Bodens angeordnet sein, so dass die Maische, oder aber auch beispielsweise Reinigungsflüssigkeit, gut ablaufen kann.The mash process can advantageously be arranged in the bottom at the lowest point of the inclined bottom, so that the mash, or even, for example, cleaning liquid, can run well.

Vorzugsweise liegt der Winkel α in einem Bereich von 4° - 10°.Preferably, the angle α is in a range of 4 ° - 10 °.

Das Maischegefäß 1 weist ein Gehäuse 2 auf, das hier in wesentlichen hohlzylindrisch ausgebildet ist. Das Gehäuse 2 umfasst einen Boden 9, der nachfolgend noch näher erläutert wird. Weiter weist das Maischegefäß 1 eine Dunsthaube 11 sowie ein Dunstrohr 14 auf. Ferner weist das erfindungsgemäße Maischegefäß einen Antrieb 13 für ein Rührwerk auf sowie einen Zulauf 4 und einen Ablauf 5 für Maische und/oder Reinigungsflüssigkeit. Optional kann auch ein Zulauf 60 für Maische, insbesondere für Trockenschrot im oberen Bereich des Maischgefäßes 1 angeordnet sein. Fig. 4 shows a rough schematic of the side view of a mash vessel 1, that is, a mash tun or a mash pan according to the present invention. The mash vessel 1 has a housing 2, which is formed here substantially hollow cylindrical. The housing 2 comprises a bottom 9, which will be explained in more detail below. Furthermore, the mash vessel 1 has a vapor hood 11 and a vapor tube 14. Furthermore, the mash vessel according to the invention has a drive 13 for an agitator and an inlet 4 and a drain 5 for mash and / or cleaning liquid. Optionally, an inlet 60 for mash, in particular for dry meal in the upper region of the mash vessel 1 may be arranged.

Fig. 1 shows a partial section through the housing 2 of the mash vessel according to the invention according to a first embodiment of the present invention.

Fig. 1 zeigt, dass der Boden 9 derart ausgebildet ist, dass er vom Umfang 15 aus betrachtet, schräg in Richtung Mittelachse L des Gehäuses 2 nach oben, d.h. in Richtung Dunsthaube zuläuft. Darüber hinaus ist der Boden 9 unter dem Winkel α zur Mittelachse L schräg in das Gehäuse 2 eingesetzt und eingeschweißt. Der Winkel α liegt vorzugsweise in einem Bereich von 4 bis 10 Grad, hier bei etwa 5 Grad. Die Schrägstellung des Bodens 9 bringt mit sich, dass der Umfang 15, d.h. die untere Umfangskante, die in das Gehäuse 2 eingepasst ist, in einer zur Horizontalebene H geneigten Ebene E liegt (siehe hierzu auch Fig. 3 a). Fig. 1 shows that the bottom 9 is formed such that it viewed from the periphery 15, obliquely in the direction of the central axis L of the housing 2 upwards, ie in the direction of the hood. In addition, the bottom 9 is inserted at an angle α to the central axis L obliquely into the housing 2 and welded. The angle α is preferably in a range of 4 to 10 degrees, here at about 5 degrees. The inclination of the bottom 9 implies that the circumference 15, ie the lower peripheral edge, which is fitted into the housing 2, lies in a plane E inclined to the horizontal plane H (see also Fig. 3 a) ,

In dem in Fig. 1 und 3a gezeigten Ausführungsbeispiel ist der Boden 9 als ein sich nach oben verjüngender Kegel ausgebildet, dessen offene Grundfläche die Mittelachse L des Gehäuses 2 unter einen Winkel von 120 > γ > 90 Grad schneidet und oval ist. Durch die Schrägstellung ergibt sich, dass die Maische auf eine Seite (in Fig. 1 zur rechten Seite) läuft, so dass ein Ablauf 5 für die Maische im Boden 9 an der tiefsten Stelle angeordnet ist. Der Kegel ist hier so ausgebildet, dass die kegelförmige Bodenmantelfläche unter einen Winkel β von 5 bis 30 Grad zur Kegelgrundfläche geneigt ist, wobei die Kegelgrundfläche offen ist, und durch die Umfangskante 15 begrenzt wird. Der Boden 9 ist vorzugsweise aus Edelstahlblech gefertigt. Unter dem Boden 9 ergibt sich der Hohlraum 10 in dem auch beispielsweise platzsparend der Antrieb für das Rührwerk 1 angeordnet werden kann.In the in Fig. 1 and 3a 9, the base 9 is designed as an upwardly tapering cone, the open base of which intersects the center axis L of the housing 2 at an angle of 120>γ> 90 degrees and is oval. Due to the inclination results that the mash on one side (in Fig. 1 to the right), so that a drain 5 for the mash in the bottom 9 is located at the lowest point. The cone is here designed so that the conical bottom surface is inclined at an angle β of 5 to 30 degrees to the cone base surface, wherein the cone base is open, and is limited by the peripheral edge 15. The bottom 9 is preferably made of stainless steel sheet manufactured. Under the bottom 9 results in the cavity 10 in which, for example, the space-saving drive for the agitator 1 can be arranged.

Im Maischegefäß ist das Rührwerk 6 angeordnet. Das Rührwerk 6 wird von der Antriebswelle 16 über den Antrieb 13 (siehe Fig. 4), der in Fig. 1 nicht dargestellt ist, angetrieben. Ferner umfasst das Rührwerk 6 mindestens einen, hier zwei sich radial nach außen erstreckende Arme 7. Die Arme 7 weisen am äußeren Ende Rührflügel 8 auf, die zur besseren Durchmischung der Maische dienen. Die Arme 7 sind nach unten gerichtet und verlaufen vorzugsweise im wesentlichen parallel zur Oberfläche des Bodens 9. Dabei ist die Rührwerkachse R ,um die die Arme 7 rotieren, d.h. die Welle 16 ,ebenfalls zur Längsachse L des Gehäuses 2 um einen bestimmten Winkel schräggestellt. Vorzugsweise ist die Rührwerksachse R ebenfalls unter dem Winkel α zur Längsachse L geneigt, unter dem auch der Boden 9 schräg in das Gehäuse 2 eingesetzt ist. Die Wellenabdichtung (Stopfbuchse) kann direkt in die Kegelspitze eingeschweißt werden. Dadurch, dass auch die Rührwerkswelle schief steht, entsteht eine erheblich bessere Rührwirkung.In the mash vessel, the agitator 6 is arranged. The agitator 6 is from the drive shaft 16 via the drive 13 (see Fig. 4 ), which is in Fig. 1 not shown, driven. Furthermore, the agitator 6 comprises at least one, here two radially outwardly extending arms 7. The arms 7 have at the outer end of stirring blades 8, which serve for better mixing of the mash. The arms 7 are directed downwards and preferably extend substantially parallel to the surface of the bottom 9. Here, the agitator axis R, about which the arms 7 rotate, ie the shaft 16, also inclined to the longitudinal axis L of the housing 2 by a certain angle. Preferably, the agitator axis R is also inclined at the angle α to the longitudinal axis L, under which the bottom 9 is inserted obliquely into the housing 2. The shaft seal (stuffing box) can be welded directly into the cone tip. Due to the fact that the agitator shaft is also tilted, a considerably better stirring effect is created.

Im Wirkbereich W des Rührwerks 6 ist der Maischezulauf 4 vorgesehen, über den Maische dem Gefäß zum Einmaischen zugeführt wird. Anstelle des separaten Zulaufs 4 könnte auch der Ablauf 5 im Boden 9 als Zulauf verwendet werden, was die Vorrichtung noch weiter vereinfachen würde. Der Zulauf könnte jedoch auch oberhalb des Wirkbereichs W im Gehäuse angeordnet sein. Eine weitere Möglichkeit bestünde darin, den Zulauf als ein von oben in das Gehäuse eintretendes ,an dem Gehäuse nach unten verlaufendes Zulaufrohr 60 zu realisieren. Eine solche Lösung ist insbesondere für Trockenschrot geeignet. Unter dem Wirkbereich W des Rührwerks 6 versteht man den Bereich, vom oberen Ende der Rührflügel bis zum Boden 9. Dadurch, dass der Zulauf für die Maische nicht mehr im Inneren des Gehäuses vorgesehen ist, sondern seitlich im Gehäuse im Wirkbereich des Rührwerks angeordnet ist, kann die Verrohrung deutlich vereinfacht werden, da Eintritte, z.B. von der Mühle am Umfang verteilt werden können.In the effective range W of the agitator 6, the mash feed 4 is provided, via which mash is fed to the vessel for mashing. Instead of the separate inlet 4 and the flow 5 could be used in the bottom 9 as an inlet, which would further simplify the device. However, the inlet could also be arranged above the effective range W in the housing. Another possibility would be to realize the inlet as an inlet tube 60, which enters the housing from above and runs down the housing. Such a solution is particularly suitable for dry meal. Under the effective range W of the agitator 6 is meant the area from the upper end of the agitator to the bottom 9. Because the inlet for the mash is no longer provided inside the housing, but is arranged laterally in the housing in the effective range of the agitator, the piping can be significantly simplified because entries, eg can be distributed by the mill on the circumference.

Das Maischegefäß 1 weist weiter eine Heizung 3a, 3b auf, die am Umfang in oder am Gehäuse 2 angeordnet ist. Dabei ist die Heizung vorzugsweise zumindest in einem Teilbereich des Wirkbereichs W des Rührwerks angeordnet, so dass auch sehr kleine Teilmaischemengen mit der Heizzarge aufgeheizt werden können. Ein beheizter Boden ist nicht notwendig. Es ist auch möglich wie aus Fig. 1 hervorgeht, dass die Heizung mehrere unabhängig voneinander regelbare übereinander angeordnete Heizabschnitte 3a, 3b aufweist, so kann gezielt in Abhängigkeit der Maischemenge geheizt werden. Verwendet man beispielsweise nur kleine Teilmaischmengen wie in Fig. 1 gezeigt ist, so ist es ausreichend, wenn zumindest in einem Teilbereich des Wirkbereichs W des Rührwerks geheizt wird.The mash vessel 1 further has a heater 3a, 3b, which is arranged in or on the housing 2 on the circumference. In this case, the heater is preferably arranged at least in a partial region of the effective range W of the agitator, so that even very small partial mixing quantities can be heated up with the heating frame. A heated floor is not necessary. It is also possible as from Fig. 1 shows that the heater has a plurality of independently controllable superimposed heating sections 3a, 3b, it can be selectively heated depending on the mash quantity. For example, use only small partial mash quantities as in Fig. 1 is shown, it is sufficient if at least in a portion of the effective range W of the agitator is heated.

Fig. 2 zeigt eine weitere Ausführungsform gemäß der vorliegenden Erfindung, die dem in Fig. 1 gezeigten Ausführungsbeispiel entspricht, mit der Ausnahme, dass der Winkel β der kegelförmigen Bodenfläche 9 unter einem Winkel von 10 Grad zur Kegelgrundfläche, die geöffnet ist, geneigt ist. Fig. 2 shows a further embodiment according to the present invention, which corresponds to the in Fig. 1 1, with the exception that the angle β of the conical bottom surface 9 is inclined at an angle of 10 degrees to the cone base which is open.

Die Form des sich in Richtung Mittelachse des Gehäuses nach oben verjüngenden Bodens ist selbstverständlich nicht auf die in Fig. 1 und 2 sowie Fig. 3a gezeigte Kegelform beschränkt. Wie aus Fig. 3b hervorgeht, kann der Boden 9 auch als ein sich nach oben verjüngender Kegelstumpf ausgebildet sein, dessen Grundfläche ebenfalls die Mittelachse L des Gehäuses unter einem Winkel 120° > γ > 90 °schneidet und der ebenfalls unter dem Winkel α zur Längsachse L geneigt ist. Die Rührwerksachse geht dabei ebenso durch die Mitte des Kegelstumpfes.The shape of the upward tapering towards the central axis of the housing bottom is of course not in the Fig. 1 and 2 such as Fig. 3a limited shown cone shape. How out Fig. 3b As can be seen, the bottom 9 may also be formed as an upwardly tapering truncated cone whose base also cuts the central axis L of the housing at an angle 120 °>γ> 90 ° and which is also inclined at an angle α to the longitudinal axis L. The agitator axis goes through the middle of the truncated cone as well.

Wie in Fig. 3c gezeigt ist, kann die Bodenfläche 9 auch eine gekrümmte nach oben zulaufende Form aufweisen, die unter einem Winkel α geneigt zur Mittelachse L des Gehäuses in das Gehäuse eingesetzt ist, so dass die Umfangskante 15 des Bodens, ebenfalls in einer zur Horizontalebene H geneigten Ebene E liegt.As in Fig. 3c is shown, the bottom surface 9 may also have a curved upwardly tapered shape, which is inserted at an angle α inclined to the central axis L of the housing in the housing, so that the peripheral edge 15 of the bottom, also in a horizontal plane H inclined plane E lies.

Wesentlich bei der Form des Bodens 9 ist lediglich, dass er vom Umfang aus betrachtet schräg nach oben zuläuft und der Umfang 15, an dem der Boden 9 in das Gehäuse eingesetzt ist in einer zur Horizontalebene H geneigten Ebene E liegt. Dabei muss sich der Boden nicht kontinuierlich oder stetig nach oben verjüngen, sondern kann auch Stufen aufweisen.Essential in the shape of the bottom 9 is merely that it extends obliquely upward viewed from the periphery and the circumference 15, where the bottom 9 is inserted into the housing in a horizontal plane H inclined plane E is located. The soil does not have to taper continuously or steadily upwards, but may also have steps.

Gemäß der vorliegenden Erfindung können also auch ohne beheizten Boden kleinste Teilmaischen behandelt werden. Auch zähe hochviskose Maischen können gut durchmengt werden. Zusätzlich entsteht noch eine Kostenreduzierung durch die entfallende Auslaufschüssel. Die Verrohrung wird einfacher, da Eintritte, z.B. von der Mühle am Umfang verteilt werden können. Auch die Bauhöhe des Gefäßes verkleinert sich, was gerade bei Sudhäusern mit niedriger Podesthöhe von Vorteil ist.Thus, according to the present invention, even the smallest part of mash can be treated without a heated bottom. Even viscous, high-viscosity mashes can be thoroughly mixed. In addition, there will be a cost reduction due to the missing outlet bowl. The piping becomes easier as there are entries, e.g. can be distributed by the mill on the circumference. Also, the height of the vessel is reduced, which is particularly advantageous in brewhouses with low platform height.
